Speed up npm

npm install can be very long, so let's try to speed up that!

Disable progress

npm config set progress false

Setting up a local cache server

Inspired from this ressource.

Installing npm-proxy-cache

sudo apt-get install -y nodejs npm
npm config set prefix '~/.npm-packages'  
export PATH="$PATH:$HOME/.npm-packages/bin"
npm install -g forever npm-proxy-cache  
ln -s /usr/bin/nodejs /usr/bin/node

Starting the cache server

sudo forever /usr/local/lib/node_modules/npm-proxy-cache/bin/npm-proxy-cache  -e -t 600000 -h localhost

You should see that the server is running on 8080 port:

[2017-05-29 13:13:11.725] [INFO] proxy - Listening on localhost:8080 [6172]

Configuring npm-proxy-cache

npm config set proxy http://localhost:8080/  
npm config set https-proxy http://localhost:8080
npm config set strict-ssl false  

Testing the cache server

cd my-app
rm -rf node_modules
npm install

Automating server boot

todo

Yeah, it works!
